Classes and Functions in  OOP (Object Oriented Programming)


In object-oriented programming, a class is a template definition of the methods and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables.
The class is one of the defining ideas of object-oriented programming. Among the important ideas about classes are:

  • A class can have subclasses that can inherit all or some of the characteristics of the class. In relation to each subclass, the class becomes the superclass
  • Subclasses can also define their own methods and variables that are not part of their superclass.
  • The structure of a class and its subclasses is called the class hierarchy.

A Simple Program defining Classes using OOP (Object Oriented Programming) is given below in which i have made a class named Student:



#include<iostream>
using namespace std;
class student
{
int rollnumber;
char name[120];
char FatherName[120];
public:
void Setstudent()
{
cout << "Please enter roll number:";
cin >> rollnumber;
cout << "Please enter name:";
cin >> name;
cout << "Please enter Father Name:";
cin >> FatherName;
}
void Getstudent()
{
cout << "Rollnumber:" << rollnumber << "\n";
cout << "Name:" << name << "\n";
cout << "FatherName:" << FatherName << "\n";
}
};
int main()
{
student s[10];
for(int i=1;i<=10;i++)
{
s[i].Setstudent();
}

}
